CIRCUIT-OPERATING DEVICE.

Specification of Letters Patent.

Patented June 25, 1907.

- Application filed August 31, 1906. Serial No. 332,798.-

full, clear, and exact description of the in vention, such as will enable others skilled in the art. to which it appertains to make and use the same.

The object of this invention is to provide an improved circuit operating device es eclally'adapted for use in connection with e alarm systems. of sim leand economical construction and adapted the use of cells.

The invention consists in the construction sh0wn, described and pointed out in the appended claims, the invention not being confined to the precise forms of the parts illustrated. I In the accompanying drawin sF-igure 1 is a view of the mechanism in side elevation; Fig. 2 is a top plan view; and Fig. 3 is a detail illustrating the device for releasing the escapement lever.

In the views 1 designates the drum of a motor and containing. a suitable power spring for driving it in the direction indicated by the arrow thereon Fig.1 One end of the drum is furnished with a head 2 having a smooth rim. except where it is provided with a notch 3. The other end is furnished with a spur gear 4.- Arranged parallel to the drum are three shafts 5, 6, and 7 geared together by a suitable train. On the shaft 5 is a si nal or number wheel 8 provided with incline teeth spaced to give a signal, as hereinafter described, when the drum is rotated. Thesignal wheel 8 is rotated in the direction indicated by the arrow thereon Fi 1. Pivoted at 9 is a horizontaI lever 9 carry.

ing a block 9* having an inclined lower edge to ride on the rim and teeth of the wheel 8. The lever 9 is held downward by means of a spring 10. Connected hingedly with the free end of the lever 9 is a vertical bar 11 hav-' ing rack teeth at its lower end.

12 is a permanent magnet and 13 is a coiled armature working between the poles of aid magnet. I

-14 is the'shaft of the coiled armature,and

to be operated without 'trical impulse in said coil.

. this shaft is provided with a spur gear lat that is engaged by the rack teeth of the bar 11.

When the rack bar is constructed to operate the wheel 14 11 the up-stroke of that bar the signal apparatus should be made incapableof operation by the weaker electro-motive force generated by the slower motion of the coiled armature produced by said up-stroke.

The'shaft 7 has a star wheel 7 that is en gaged by an ordinary escapement 15 aflixed to the shaft of which is an arm 15* carrying a lateral pin 15'.

16 is a lever pivoted at 16 and havlng a handle at one end and a dog 16 at the other arranged to engage the notch 3 in the head 2 of the drum. The lever 16 also has a sto 16 that, when the dog 16 is engaged with the notch 3, lies. in the path of the pin 15 and prevents vibration of the escapement arm 15 and therefore the operation of the escapement. The lever 16 .is held with its dogged end down by means of a spring 17.

Assuming that the power spring for operating the drum 1 has been duly wound and it is desired to send a signal, the operation is as follows: Upon pulling down the handled end of the lever 16 and lifting the dog 16 out. of the notch 3 the escapement is permitted to operate as is usual with escapements. The signal wheel 8' is rotated and the lever 9 intermittentl oscillated by the teeth of said wheel 8. ecause of the construction of the teeth of the Wheel 8 and the rider block 9 the downward movement of the lever 9 and consequently of the bar 11 is quick and hence imparts a quick rotation to the shaft of the armature coil 13. thereby generating an elec- This impulse is conveye by suitable conductors 13 to a gong or other signaling device. vIn the instance shown the wheel 8 is provided with seven teeth arranged to signal the number 232. The dog, when lifted. out of the notch 3 to send a signal and after the drum has moved a little, may be allowed to ride on the smooth rim of the head 2, and to automatically drop into said notch upon a complete revolution of said head. The circumference of the gear 4 may be to the small gear it engages as five is to one, in which case the Wheel 8 will be revolved five timct in one revolution of the drum and the same signal given'that number of times.

What I claim and desire to secure by Let ters Patent is:

In a circuit-operating device, the combination of a motor, a signal Wheel driven thereby, an electromagnetic generator, and means for operating said generator by the signal wheel.

2. In a circuit-operating device, the combination of a motor, a toothed signal wheel driven thereby, a lever carrying a rack bar said lever being actuated by said toothed Wheel, an electromagnetic generator including a coiled armature having a shaft, and. a pinion on said shaft engaged by said rackbar.

3. In a circuit-operating device, the combination of a motor, a signal wheel driven thereby, an electromagnetic generator, means for operating said generator by the signal wheel, an escapement for controlling the operation of the motor, and means for automatically stopping the operation'of the escapement.

4. In a circuit-operating device, the combination of a motor, a signal Wheel driven thereby, an electromagnetic generator, means for operating said generator bythe signal Wheel, an escapement for controlling the operation of the motor, means for manually releasing said escapement and automatically stopping its operation.

5. In a circuit-operating device, the combination of a motor, a s gnal Wheel driven thereby, an electromagnetic generator including a coiled armature, and means between the generator and the signal wheel adapted to give intermittently-quick movements to the armature of the generator.

In testimony whereof I afliX my signature, in presence of two witnesses.
